Mysql存储过程包含事务,且传入sql数据执行_MySQL

mysql sql statement dynamic

有这样一个需求,要求在mysql存储过程中使用到事务,而且执行的是动态的sql语句

代码如下:

BEGIN	DECLARE in_data TEXT;	  /** 标记是否出错 */    DECLARE errno INT DEFAULT '0';    /** 如果出现sql异常,则将t_error设置为1后继续执行后面的操作 */    	DECLARE CONTINUE HANDLER FOR SQLEXCEPTION BEGIN ROLLBACK;SET errno = 1; END;	START TRANSACTION;  	-- 传入的语句处理过程	PREPARE stmt FROM @in_data;	EXECUTE stmt;	IF (errno =1) THEN          ROLLBACK;   ELSE          COMMIT;  		END IF;  	SELECT errno;END
Copy after login
调用 :
SET @in_data = 'insert into accounts (`userid`,`password`) value (122222222,2),(22222,11)';CALL SYN_Updata(@in_data);
Copy after login
其实这个存储过程只要是用到事务的地方都可以用到,因为执行的条件是动态的。
